Smart Charging

Automatically managed charging.

Load Management System (LMS)

A system necessary for the management, monitor, coordination and allocation of the load for each charging point connected. Standard element for smart charging.

Power Management System

A system necessary for capturing, managing and controlling the source power, such as Shadow Power, for EV charging points. This is not a standard function from the smart charging systems in the market.

Super Load Management System (SLMS)

SLMS is a LMS but it performs better and more functions than common LMS in the market. It not only conducts genuine dynamic load management, in which the charging power for a fully-charged EV can be released to boost the rest of EVs in charging, but is also capable of performing management on the power source side. The PSN-EVC system is a Super Load Management System rarely found in the market.


Power System Neutral (PSN) is a unique power management system developed for the capturing and management of Shadow Power. 


EV Charging (EVC) acts as a load management system for smart charging. 


A comprehensive system comprises of a standard SLMS (EVC) and a PMS (PSN) as a bonus for smart and green EV charging solution.
